2. Enter “99” and wait for “reset” voice prompt.
3. Enter the encoded MAC address (Look below on how to encode MAC address).
4. Wait 15 seconds and device will automatically reboot and restore factory settings.
Encode the MAC Address
1. Locate the MAC address of the device. It is the 12 digit HEX number on the bottom of the unit.
2. Key in the MAC address. Use the following mapping:
0-9: 0-9

Reset from web interface (Reset Type)
1. From the Advanced Settings Page user can select three types:
Full Reset: This will make a full reset
ISP Data: This will reset only the basic settings, like IP mode, PPPoE and Web port

NOTE:
1. Factory Reset will be disabled if the “Lock keypad update” is set to “Yes”.

restart the unit. The device will not return to factory default settings.
